s'rAMrING Ann SEALING- MACHINE.

Application filed May 2, 1925. Serial No. 27,566.- i

This invention relates to a device for stamping and sealing envelopes, the general.

object of the invention bemg to provide-a receptacle in which the envelopes are placed means for feeding the envelopes one by one upon the conveyor and moistening the flaps as they pass to the conveyor, means. for affixing stamps to the envelopes from a row of stamps andmeans for applying pressure to the envelopes to cause the gumzned portions of the flaps to adhere to the. envelopes.

This invention also consists in .certain' other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in i the appended claims. 7 7 r i In describingmy invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding partsthroughout the sevrangement ofthe shafts.

' Figure 9 is an end view showing section on line H of Figthe ar- 3 In these'vie-ws, '1 indicates a base and 21indicates a plurality of upright-s; for supporting the various parts of the apparatus. Am envelope containing receptacle 3 is supported from some'of theuprights'by a bracket 4 thisreceptacle being preferably formed 0 wire mesh 'with its lower part contracted at its fronhas shownat 3: A frame 5- is placed aroundthe upper portion of the receptacle and a pair of'stubshafts'ti are carried bysaid frame, one at each side thereof and a disk 'T is fastened to each shaft, each disk having a slit '8 therein witha portion adjacent the slit "being curved upwardly and given a beveled edge, as shown at 9; These disks eiitend into the receptacle and Wlll support device.

with parts in seethe envelopes, shown-at A,tl1erein and when the disks are rotated the beveled edges will engage the lowermost envelope and separate inches.

it from the other envelopes and after the disks have made a complete revolution, the envelope Wlll be freed from the disks and will drop to the lower part of the receptacle. The stub shafts are provided with pulleys 10 which are connected by the belts 11 with the pulleys 12 on the cross shaft 13 carried by one of the uprights and said shaft is driven from a shaft 14 by means of the belt 15 and the pulleys 16- and this shaft l l is in 7 turn driven from a shaftl'? by means of the belt 18. and-the pulleys 19 aridtheshaft 17 is driven from the conveyor shaft 20 by means of the belt 21 and the pulley 22. This similar roller 24 is carried by the shaft 25 conveyor shaft 20=carries a roller 23 and a supported in uprights at? theother end ofthe The conveyor belt 26 which passes over the rollers 23 and 24fis provided with the strips 27 and said conveyor is arranged to pickup the envelopes discharged. from the receptacle 3 and carry .themto the'stamp applying means. i

As the envelope drops diskflt be caught by the pins 30in the lower part of the receptacle and by a roller '31 which is arranged in .a tank 82, this roller engaging the extended flap a of the envelope sons to moisten the same. The envelopes. are held on'the pins by the. jaws v60 on a. rock shaft 61 which has a pinion 62- thereon engaging with a'rack 63 which is reciprocatedin its housing 64 by disk 65 on shaft 1% through the pitman 66. These parts are so arranged thatwh'en the envelope drops uponthe pins 30,the shaft will be rocked so "that theprojections 60 will grip thedenvelope between themselves and the pins- 30. The envelope is knockedfrom the pins 30 and roller 31. by

a rod 33 which is carried bythe pivoted arm 34, the arm and rod being given a rotarymovement by-means of the link 35 which is connected with the crank 36 fastened'on the shaft ll. This rod 33 will firstlstrike' the flap of the envelope and will fold the same over upon the rear .of the; envelope, cans.- ing the flap tospass, over the moistenlng roller and causing the envelope to descend upon the conveyor belt 26. Just as the. rod

is moving; the. flap toclosed position,- the e jaws 60 will be moving'to open position so that the envelope will be released on the final movement of the rod so that the envelop'ecan drop upon the conveyor.- This belt -will then take the envelope to the stamp affixing means. Such means comprises a large Jroll 37 carried by the stub shaft 38 and havand which is arranged in a tank 42 so that I it'will moisten the stamps.

1A small cutter roll 43 is arranged to cut the stamps from the strip at a pointhelow the roll 41, the knife of such cutter roll engaging the notches 39. The severed stamps will drop upon the envelope and then. the

envelope passes under the presser block 44 carried by the presser arm 45 which is normally pressed downwardly by the spring 46 placed onthe stem .47 of the arm and pressing against a part-48 of the frame, the arm belng raised by the cam 49 on the shaft 25 of the roll 324, the arm being provided with asmall roller 50' forengaging the cam.' A spring 51, placed on the stem 47 above the part 48, tendsfto cushion the downward 'movement of the stamp allixer, this spring having less tension than the spring 46. This press'er mechanism is arranged above the plate 52 carried by the frame so that the portion of the envelope'carrying the stamp is pressed between the block and this plate 52 This plate 52*directs-the envelope between the presser rolls 53 and 53 which will press the flap firmly against the body of the envelope and'thus seal the envelope. The

upper roll 53 carries the roll v4O for the "strip of stamps and has its bearings pressed downwardly by the springs 54 which causes I the roller 53 to be pressed against the roll :53 lower springs, 54 acting as' cushion means for the parts. The rollers 53 and 53 are-connected together by the gears 55 and the shaft of one of the compression rolls is connected to the motor 28 by the driving connections 29. and the other shaft is belted to the shaft 25', as shown at 56. The roll is belted to the roll 53, as shown at 56.

s From the foregoing it will be seen that the envelopes when placed in the receptacle with their flaps in open position and the apparatus started up they will be fed one 'by'one through the receptacle 'where their flaps are moistened and folded and then the envelopes. will drop upon the conveyor and be conveyed to the stamp afiixing device and then to the compressionrollers where they 2 f will be sealed; Thus the device will automatically stamp and seal envelopes and at great speed. v 7

Each pin 30 carries a" spring 30 which has a strip of rubber or the like at its upper end for engaging a jaw 60. The envelope is gripped between the jaws and the springs on the pins 30 and these springs would-cause the jaws to grip the envelope before the jaws touch the pins andthey enable the'enroller so that the roller is always moist.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that 1, may

make changes in the constructionand in the combination and arrangement of the several,

parts, provided that such changes fall withinthe scope of the appendedclaims';
